To ALL WHOM IT MAY CONCERN:

Be it known that I, EDWARD ATKINSON, ofBrookline, in the county of Norfolk, and State of Massachusetts, have invented certain new and useful improvements in the Machinery or Apparatus Whichis used for Worlring, Grinding, or Preparing Peat, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, muking'purt of this speeificatioinin which- Figure 1 is a longitudinal vertical section.

Figure 2, a transverse section.

Figure 3, a-rear end view; and

Figure 4, a side elevation of the operating cylinder.

My invention consists in the employment of certain plough-shaped cutting and turning blades of'mouldboards, it, arranged spirally upon and secured to the surface of the cylinder .13, and in combination" therewith, of certain cutting blades, e, which may be arranged between the plough-shaped blades in straight or spiral rows. In combinationwith .these plough-shores and cutting blades my invcntion consists in the employment of a deep cut course-threaded screw, either fitted to the conical-end of the cylinder, or formed in the substance thereof. 7 y

l Iy invention also consists in. a yielding or an expanding outlet, -A,'urrunged ut the rear end of the machine, the yielding sides 0, of which are made of thin steel plate, or other materialwhich will spring or yield outward, when the ground and prepared or pasty substance is being forced'out between saidyieldihg sides. This outlet maybe made of some elastic or expanding substance, or tube of like soft rnbbeiyend when the pasty substance is being forced out, the yielding or the expanding outlet willallow the compressed pasty substance to expand as it leaves the outlet, and thereby prevent said substance or prepared'peat from cracking, as it would do if the outlet was straight'and unyielding. It is exceedingly-important to preventthe prepared and compressed peat cracking,, for when exposed for drying-in the open air, it is liable to be wet by showers of rain, and then the water would run, into cracks und'very much retard the drying process, and injure the prepared peat. i

The rough peat is thrown into the hopper G, the cylinder B rotating 'by power applied to the pulley D or other device, the plough-shaped blades or plough-shares a cut and turn said rough peat over, andzmoveit along into contact with the blades c, which slice, out, and chop it into small fragments,and as the blades 0 are cutting.

and chopping said peat, the plough-shares are turning it over intocontact with other cutting blades along the straight portion of the cylinder, where the plough-shares hearest the screw turn the substance over and push it along into contact with the course threads of the screw, which jam, mash press, and force said substance or peat along 'the inclines or angular sides d of the case, and out at the rear-end between the yielding sides 'e of the'ontlet, or through an expanding tube, f.- By this operation of the plough-shares andcutting blades, the rough peat is pressed, cut, ja.mmed, and recut to a considerable degree of fineness, along the straight portion of the cylinder, which cylinder may be of any suitable length to cont'ain the requisite number of plough-shares and cutting blades to performthe operation in a satisfactory manner; and by the operation of'the coarse screw, the cut and. jammedsubstan'ce is ground, crushed, and mashed to a pasty condition and forced-out throughthc yielding or expanding outlet, in the proper form to be dried for use; It will bra-observed. that-the'doors E may be opened by releasing the springs m, which hold them against any hard bunches or uncut substance, but give Way to allow such bunchy substance to. pass, if caught on either of the plough-shares or blades I urn aware theta-screw has been used for grinding or. preparing peat, and that a fixed and permanent or stationary and unyielding outlet, or delivery having abflariug end, has been'used to prevent prepared peat cracking. I am also aware that a rotating conical screw-fincombinationiwith a. conical straining vessel, has been used for separating the decomposed from the fibrous portion ofpeat. Therefore I wish it to; be distinctly understood that I disclaim hnving'inventedthe equivalent, in principle or operation, of either of the above-named devices; but what I do claim as new, and desire to secure by Letters Patent, isi 1. The combination of. plough-shares a, cutting'blades c,'andconical screw. constructed and arranged to operate substantially as and for the purpose set forth.

2. The yielding or cxpanding outlet or delivery tube, arranged to operate substantially as. and for the cf th. I purpo ic EDWARD ATKINSON.
